文79-10块难动用储量开发技术研究

文79-10块隶属于文79断块区,该块构造相对比较简单,主要含油层系沙二下1-4、沙三上1-4。含油面积0.38km2,地质储量42.5×104t,油藏埋深2900~3450m。含油高度小,揭示程度低,储量一直未落实。2011年我们以"油藏评价、产能建设、注水配套"三位一体的工作思路,本着探下部层系兼顾上部井网的原则,加强油藏分布规律认识。在充分认识油气层纵向分布特点的基础上,对重点区块主要目标层段进行精细构造解释评价,达到地震、井两者间的有机结合,提高解释精度。     

利用数模优化临106-1断块配产配注

临106-1断块位于临盘油田临13断块区,为4条断层所控制的断鼻式圈闭。含油面积0.34 km~2,地质储量57×10~4 t,标定采收率27.8%。含油砂组1-2砂组,含油小层10个,油层埋深1780～1840m,为典型的复杂断块多层层状油藏。断块主要存在两个问题:平面流线不均衡层间干扰严重;小层动用差异大,常规配产配注已不能满足目前开发需要,为此我们对该块开展了建数模工作,在储层、剩余油研究的基础上利用数模技术对油井配产,水井配注进行优化,达到均衡水驱,提高采收率的目的。

濮城油田分类油藏挖潜思路

濮城油田是一个埋藏深、含油层系多、油藏类型多、非均质性严重的断块油气田，油藏非均质性严重，出程度高、主力层水淹严重，迫切需要加强层间转换工作。到2007年，油田共发现沙一、沙二上、沙二下、沙三上、沙三中、沙三下、沙四上共七套含油气层系，探明含油面积79．31km^2、石油地质储量15964．82×10^4t，目前已动用含油面积75．1km^2，石油地质储量15091．1×10^4t，石油地质储量探明动用率94．539／6，标定可采储量5106．82×10^4t，标定采收率33．84％。2008年我们在对油藏的整体研究的基础上，制定了一套符合油田发展的精细注采调整方案。

梁11-63井组潜力分析及下步挖潜措施研究

梁11-63井组位于梁11断块中区,主要含油层系为沙二7、8砂层组。含油面积0.34km2,地质储量150×104t,可采储量82.2×104t,最终采收率54.8%。梁11断块为常温、常压、中高渗透岩性构造断块油藏。纵向上渗透率差异较大,层间非均质性较严重。目前进入含水上升阶段,井组产量递减快,注采井网不完善,地层能量下降快,为此针对梁11-63井组目前存在的问题进行分析,进一步发掘潜力,并提出了下步挖潜措施,为梁11-63井组更好的开采提供了可靠的依据。     

重复压裂裂缝延伸控制技术在卫360块的先导性试验

卫360块位于东濮凹陷中央隆起带卫城构造东北部,主要含油层位沙三中、沙三下,地质储量556×10^4t,可采储量10^4×10^4t,属低渗常压油藏,自2002年投入开发以来所有储层均为压裂投产,目前地层压力系数已下降至0．8左右。老井重复压裂将成为该区块一项重要的油井增产措施。重复压裂裂缝延伸控制技术是应用化学暂堵剂暂堵老缝或已加砂缝,使裂缝延伸方位与原裂缝发生一定角度的偏转,纵向上启动新层,改善油藏产出剖面;平面上裂缝转向,沟通新的泄油区。为提高卫360块压裂增产效果,在该区块卫360-10井进行了重复压裂裂缝延伸控制技术试验,取得了较好的效果,为下步区块老井压裂增产提供了技术支持。

Synthesis and characterization of homopolymers and copolymers of various acrylates and acrylonitrile

Various homopolymers and copolymers of methyl acrylate, ethyl acrylate, butyl acrylate, and acrylonitrile in different feed ratios were synthesized. These were characterized by IR, ¹³C-NMR, DSC, DTA, and TGA. Spectroscopic characterization helped in differentiating copolymers of different mol ratios. Thermal analysis revealed different degradation patterns for homopolymers and copolymers. The temperature and energy changes associated with various phase transitions were dependent on the chemical composition of homo- and copolymers, as expected. © 1993 John Wiley & Sons, Inc.

Comparison of the Adhesion and Cohesion of Triblock and Random Copolymers of Styrene and Butadiene

A substantially greater detachment energy is required to strip a polyethylene tereph-thalate (Mylar) film from a styrene-butadiene-styrene (SBS) triblock copolymer compared to that for peeling from a random styrene-butadiene (SBR) copolymer. This is true even though the intrinsic interaction between the Mylar and each elastomer is expected to be similar because of their virtually identical chemical composition. It is proposed that this difference in peel strength (between the SBS and SBR) is a consequence of the much higher dissipative capacity of the former elastomer. Another manifestation of this is the higher cohesive tear strength of the SBS compared to the SBR. Extents of energy dissipation within each elastomer during detachment of the Mylar adherend are consistent with the hypothesis that the average maximum stress experience before detachment is some similar fraction of each elastomer's tensile strength.     

Kinetics and Mechanism of Oxidation of Mono- and Polyacetals

Abstract

Kinetics and mechanisms of oxidation of 6 acetals by molecular oxygen and ozone in liquid phase have been studied. Reaction with molecular oxygen (70°C, 15–16 hr) leads to the formation monoethers of the corresponding glycols with 68–90% selectivity. Salts of metals and complexes with crown-ethers have increased the reaction rate significally. Ozone have reacted with acetals with formation similar products. The mechanisms of intermediate stages have been proposed.

Electronic structures and reactivities of monometallic and bimetallic clusters of Au and Cu

The variation of the Au 4f binding energy of Au clusters with the cluster size has been established by measuring the binding energies of clusters whose size distributions were independently determined by HREM and STM. The binding energy increases significantly when the cluster size is less than 2 nm. Au-Cu bimetallic clusters of the composition Cu₃Au have been deposited for the first time on carbon substrates. The shifts in the core level binding energies of the bimetallic clusters show the effect of alloying in the case of large clusters, but show effects of both alloying and cluster size in the case of the small clusters. The interaction of CO with Cu₃Au clusters is stronger than with a bulk Cu metal. The interaction of CO with small Cu clusters also seems to be stronger than with bulk Cu or with large Cu clusters.     

Wetting properties of homopolymers and copolymers of pentafluorostyrene and methylacrylate and homopolymer blends

Polypentafluorostyrene (PPFS), polymethylacrylate (PMA), and poly(pentafluorostyrene-co-methylacrylate), poly(PFS-co-MA) were prepared and the wetting characteristics of polymer blends of PPFS and PMA were compared with that of poly(PFS-co-MA) via contact angle measurements. The critical surface tension of polypentafluorostyrene was found to be 22.6 dyne/cm, which is comparable to the value reported for polytrifluoroethylene (22 dyne/cm). The critical surface tension of poly(PFS-co-MA) is not linearly related to its composition. The polymer blends of PPFS and PMA exhibit significant surface enrichment of the fluoropolymer. The harmonic-mean method¹ was employed to determine surface tensions of these polymers and many known polymers. It is found that the method produces useful surface tension data provided the contact angle values are derived from testing liquids of dissimilar polarity.
