粘土矿物成岩作用对油气储集性和产能的影响——以苏北盆地台兴油田阜三段储层为例

该文基于12口井的粘土矿物X-衍射、岩心铸体的测试数据及电镜扫描微观图象观察,对台兴油田阜三段4个油组储层的粘土矿物类型及分布特征进行了研究,阐述了粘土矿物类型与储层面孔率及孔喉结构的关系,分析了粘土矿物转化与孔隙演化的规律、粘土矿物产状对储集性的影响,同时对开发中粘土矿物成分对油层和产能的影响进行了分析。研究结果表明高岭石含量与孔隙度成正相关关系,绿泥石、伊利石的含量与孔隙度成负相关关系,尤其是绿泥石对孔隙度的负面影响较大,次生孔隙发育带基本相当于粘土矿物第一迅速转化带,其埋深为2350～2750m。最后对本区有利于次生孔隙发育的层位进行了预测。

安丰平1井合理生产压差的确定

根据安丰地区K2t1^3的油井生产资料及其油井试油时产量较高，但油井在生产后见水较快的特点，以控制生产压差，避免油井早期见水为原则，利用水平井的产能模型与临界产量模型计算出安丰K2t1^3地区安丰平1井的合理生产压差，分析了污染对该水平井产能及生产压差的影响，并由此反映出水平井开发中油层保护的重要性。     

Primary productivity in a deep sewage stabilization Lagoon

Primary productivity and production measurements and their relationship to observed variations in the concentrations of nutrients (N and P), CO₂, pH, temperature, dissolved oxygen and solar radiation were studied in an 8 m deep sewage stabilization pond from October 1986 to December 1987. Two types of tests were carried out: short-term and long-term. The latter permitted the transformation of short-term measurements into daily measurements and the obtention of the relationship between the time of day and primary production. The measurement of primary production was performed using the ¹⁴C technique.

The highest primary productivity values were detected during the spring-summer period, which was characterized by high temperatures and an increased degree of solar radiation. The maximum value was obtained during June (14.38 mg C mg Chl⁻¹ day⁻¹) and was accompanied by: (a) a decrease in the concentration of nutrients (N and P) and CO₂, (b) an increase in pH levels and dissolved oxygen concentrations and (c) a significant proliferation of cyanobacteria (which indicated a low organic loading).     

影响露天矿生产能力的因素分析

露天矿的生产能力不仅与矿体大小有关,而且与矿体分布的形状、推进过程中挖掘机的所在位置及生产工艺流程的是否通畅相关,是生产中综合因素互相配合的体现.     

Productivity optimization of cellular manufacturing systems

A two-stage CM productivity model is proposed. In the first stage, a 0–1 integer programming model is developed to design CM system. In this model, part families and machine cells are formed simultaneously. In the second stage, a total productivity model for CM systems is developed to optimize the total productivity of manufacturing cells by further using the unutilized machining time available on various machines. An example problem is illustrated.

大庆油田三元复合驱矿场试验动态特征

相对于其他提高采收率方法,三元复合驱对原油性质和油藏性质更为敏感。为此,大庆油田在室内研究成功的基础上,先后进行了5个三元复合驱矿场试验,研究了不同油藏特性、不同井距和不同配方的三元复合驱特征。试验结果表明,与聚合物驱相比,三元复合驱过程中注入能力下降幅度低,采出能力和综合含水的下降幅度大,在低含水期出现了乳化和结垢现象,三元复合驱比水驱提高采收率20%以上。尽管注采能力下降,但由于含水率大幅度降低,所以三元复合驱仍保持了较高的采油速度.     

Raymond Abraham Katzell (1919-2003).

Obituary of Raymond Abraham Katzell (1919-2003) who was renowned for exploring the influence of attitude and leadership on productivity and job satisfaction. Among other things, the obituary notes that in 1965, Ray Katzell and Richard S. Barrett readdressed the issue of testing inequities by asking whether psychological tests--used in employee selection--were equally valid and fair for use with various ethnic groups. With Ford Foundation support, they compiled and analyzed relevant data already available in years of company records. Their findings that such employment tests may, indeed, not always work to the same advantage for all ethnic groups were published in Testing and Fair Employment (Kirkpatrick, Ewen, Barrett, & Katzell, 1968). This book led to Ray's chairing the Department of Labor's Advisory Committee on Testing and Selection, which was influential in the drafting of Office of Federal Contract and Compliance and Equal Employment Opportunity Commission testing guidelines.

Sources of social support and burnout, job satisfaction, and productivity.

Social support has been identified as an important correlate of a variety of work outcomes. Support from different sources, including family, coworkers, and supervisors, was examined in 211 traffic enforcement agents (92 men, 119 women). Outcomes included subjective variables (burnout and job satisfaction) and an objective measure of productivity (number of summonses). Support was negatively associated with burnout and positively associated with satisfaction and productivity. A cluster of support variables accounted for 7% of the variance in burnout and productivity and 12% of the variance in job satisfaction. Family support was more closely associated with burnout than with satisfaction or productivity, whereas immediate supervisor support was related to satisfaction and productivity but not burnout. Results suggest that support may be associated with work-related outcomes through multiple pathways. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
