锦7块是典型的边底水普通稠油藏,区块经过22年的开发之后通过精细地质研究,综合运用单井小层对比、三维地震等技术重新落实构造,通过静态录井测井资料、动态生产资料分析以及监测资料找水等方法,对本块的资源量及剩余油分布空间和储量重新落实之后,在区块的中北部发现了一个新的四级断块——锦7-33-28块,并对其进行了综合调整。该块的发现,不仅提高了区块的储量动用程度和采收率,并对同类油藏蒸汽吞吐后期提高区块开发效果具有借鉴意义。 相似文献

肇294西块2007年投产初期就暴露出含水较高,与临近开发区块同期对比,高出30多个百分点,后期分析得出是由部分井产地层水所致。本文通过对产地层水井水质化学特征、分布特征、构造特征、电性特征进行深入的研究、提出了该区块产水层的识别方法,并给出了治理措施及对策,以便达到降低无效采出,改善区块开发效果的目的。 相似文献

玉北区块是西北油田分公司在和田区域的一块新探区,该区块钻井难度较大,很多井队在该区块施工期间均遇到或多或少的问题,地层阻卡、井壁失稳、盐膏层钻进、地层漏失等问题严重制约着该工区的施工进度 相似文献

沈67块为注水开发区块,目前已到了中、高含水期。随着注水的持续开发,该块油藏相对的高渗透、大孔道层段又起主导作用,使得注水延大孔道方向前进,导致油井含水上升速度较快,水驱油效果变差。我们通过对该区块储层物性及开发历史研究分析,结合油水井目前生产动态变化情况,改变常规控水稳油开采方式,实现通过调增配水不断洗油的良性循环,实现区块水驱采出程度的提高。 相似文献

为了搞清高76区块油水井连通情况,找出井间存在的大孔道或高渗层,弄清油藏平面与纵向上的非均质性,在该区块开展了示踪剂井间监测,为下步开展区块精细注水开发提供比较确切的地质依据。 相似文献

Solid solutions of diphosphates of zinc and copper and of zinc and cobalt were synthesized from mixtures of pure diphosphates at temperatures up to 1000°C. Their X-ray diffractometry patterns varied continuously from one end member to the other. Solid solutions of orthophosphates of composition Zn3−x Cox(PO4 )2, with x = 0.4–1.6, were formed at temperatures up to 950°C; all exhibited the structure of γ-Zn3 (PO4 )2. Solid solutions of orthophosphates of composition Zn3−x Cux (PO4 )2 exhibited more-complex behavior. At 1000°C and copper contents of 20–80 mol%, a phase that is related to Cu3 (PO4 )2, termed here the "ε-phase," predominated. At 850°–950°C and in the region from 20 mol% to ∼33 mol% of copper, the solid solutions (the "η-phase") adopted the structure of graftonite. At 800°–900°C and 10–15 mol% of copper, the solid solutions exhibited a new structure (the "δ-phase"), which we found to be related to the mineral sarcopside. At temperatures 950°C, the solutions that contained 5–15 mol% of copper (the "β-phase") had the structure of β-Zn3 (PO4 )2, whereas at 800°–850°C, solutions with 5 mol% of copper (the "-phase") exhibited the structure of γ-Zn3 (PO4 )2. Attempts to synthesize Cu+ ZnPO4 and Cu+ Cu2+ Zn3 (PO4 )3 were unsuccessful. 相似文献

Gel permeation chromatographic (GPC) and thin-layer chromatographic (TLC) studies of polystyrene, polybutadienes (BR), and their copolymers (SBR) have been carried out. GPC primarily separates them on the basis of molecular size, and TLC, on the basis of composition. Methods of obtaining absolute molecular weight distributions for BR and SBR based upon variations of the Strasbourg Universal Calibration procedure are described. In particular, [η]–M relationships in both the GPC solvent (THF) and in a second solvent (toluene) were used; in addition, results of statistical mechanical calculations for \documentclass{article}\pagestyle{empty}\begin{document}$\overline {s^2 }$\end{document} (based on the assumption of negligible steric hindrance and freely rotating bonds) were applied. An experimental comparison of these methods was carried out, and use of the [η]–M relationships for both solvents was found to give satisfactory results. The predictions of the statistical theory were too low. A detailed study of polymer–solvent–gel interaction in the GPC unit was made through investigation of ternary phase equilibrium in the (polystyrene)–THF–(polymer) system. The polymers studied included BR and SBR with varying styrene contents. Experimental techniques for TLC separations of BR, SBR, and polystyrene according to the composition are described. 相似文献
