海14-18块是位于海1块北部断层附近的复杂小断块,针对该块油藏认识程度低、注采井网不完善、长期低速开发的现状,开展了构造精细研究、测井二次评价、注采井网优化等研究,确定了分层系开发思路。实现新增含油面积0.33km~2,新增地质储量151.3×10~4t,部署实施加密调整井14口,断块日产油达到105t,采油速度1.36%,复杂断块得到有效开发。
The sea blocks 14-18 are complex small fault blocks located in the northern part of a block of the sea. In view of the low level of understanding of the block and the imperfect injection well pattern and the long-term low-speed development, Sub-evaluation, well injection network optimization studies, to determine the development of stratified line of thinking. The newly-added oil-bearing area is 0.33km ~ 2, and the new geological reserve is 151.3 × 10 ~ 4t. 14 wells of encryption adjustment wells are deployed and deployed, the daily oil production of the block reaches 105t and the oil recovery rate is 1.36%. The complex fault blocks are effectively developed.
