乾130区块潜力分析与稳产上产研究
摘要
乾130区块目前开发动用的油层为高台子油层。该区含油井段长,目前存在局部井网不完善、产量递减大等问题。对地质开发研究投入少、认识程度较低,特别是储层分布规律不清。本文利用了地震、钻井、测井、试采、生产等资料,开展了构造、储层、资源、开发区开发效果、调整区与外扩区井网等研究,在此基础上,指明了区块调整和外扩潜力,并优选了潜力区块和规划部署了井位及产能建设,取得的主要成果如下:
1.利用钻井、地震资料重新落实高台子油层顶面构造及断层走向和分布。
2.油层划分对比:对现有井进行重新对比和刻画。绘制砂岩、有效厚度分布图,分析了油砂体的分布特征。
3.储层岩性、物性特征:利用取心、测井等资料,对储层岩性、物性进行评价。
4.利用取心井细分沉积微相,建立了单井沉积微相划分模式,完成42个小层微相平面展布图。
5.确定了有效厚度划分的电性标准,并划分有效厚度和储量计算。
6.对已开发区进行产油、含水变化、产量递减规律等进行认识与评价。
7.开展了井网适应性的评价、合理井网密度的论证、井位部署、开发指标预测等。
8.对未补孔压裂的潜力层进行了分析和筛选。
9.明确了区块外扩与开发区加强有效注水,是今后实现稳产与上产的重要手段。
The development of the oil reservoir of the block of Qian 130 is Gaotaizi now. Long section of the area with oil wells, existing local patterns are imperfect, the decreasing of production is big. Small investment in geological research and development, low level of awareness, especially reservoir distribution unclear. The project made use of seismic, drilling, production test, production, etc, carry out the construction, reservoir, resources, development zone effects, adjust the area and expand the area well outside the network and other research, on this basic, pointing out block adjustment and external expansion potential, and potential optimization of the block and planning the deployment of a well location and capacity building, the main results obtained are as follows:
1. Use of drilling and seismic data to re-implement the top Gaotaizi reservoir and distribution structure and fault strike.
2. Reservoir subdivision and correlation: Comparison of existing wells and re-characterization. Draw sandstone, effective thickness distribution, analysis of the distribution of the oil sands.
3. Reservoir lithology, physical properties: use of coring and logging data, reservoir lithology, physical property evaluation.
4. Segmentation using coring microfacies, sedimentary single well established micro-phase model, complete with 42 small layer of the planar micro layout.
5. To determine the effective thickness of the electrical standards, and the division of the effective thickness and the reserve calculation.
6. On oil production have been carried out zone, water content changes, such as for understanding the law of diminishing production and evaluation.
7. To carry out the evaluation of the well network adaptability, reasonable argument well density, well planning, development index forecasting.
8. Not fill holes on the potential of fracturing layers were analyzed and screened.
9. Clear the block outside the expansion and strengthening effective water injection zone is stable and on the future realization of an important means of production.
