温西六区块井网加密方案研究

THE DESIGN OF WELL PATTERN THICKENING PROGRAM FOR BLOCK WENXI6

本次研究在以往油藏和地质认识的基础上,结合沉积微相研究成果,通过油藏、地质、数模、测井等多学科协作攻关,揭示了开发存在的主要问题,对地质特征进行了再认识,运用动态生产资料及各种监测资料,动静态结合,研究了目前井网适应性,论证了井网加密的必要性、可行性,确定了井网加密的总体思路、调整对象及目标,编制了三套加密调整方案并进行了开发指标预测,通过技术、经济指标对比优选,推荐了实施方案,经现场实施,取得了较好开发效果。

The problems existed in the development of this block was clarified and the geologic characteristics re-identified through the integration of sedimentary microfacies research and multidisciplinary technology(reservoir engineering, geology, numerical simulation, logging) on the basis of previous understanding of the reservoir and geology. The suitability of the existent well pattern was studied by use of dynamic production data and various monitoring data, and the necessity and feasibility to thicken well pattern was demonstrated. Three sets of well pattern thickening program were designed and through comparison of technological and economic indexes, one program was recommended. The complement of the program gained good effects.
