研究欢喜岭油田欢60块沉积特征、油层、砂体的分布及开采特点和规律,并对直井开发效果进行评价,对欢60块油井井况差,油井利用率低,整体采出程度低的问题进行分析,利用水平井泄油面积大,生产压差小、具有防砂、抑制边底水的特点,充分动用该块的难采储量,以达到提高该块采出程度的目的,经过分析论证和已完钻水平井生产效果,证明利用水平井吞吐开发是目前技术条件下唯一有可能有效动用该块难采储量的开采方式,对辽河油田稠油油藏的有效开发具有借鉴意义。
The sedimentary characteristics, distribution and characteristics of oil and gas reservoirs and sand bodies in Huanxiling Oilfield are studied, and the effect of vertical well development is evaluated. The well conditions of Huanhuan Oilfield are poor, the well utilization rate is low and the overall recovery level is low Problem analysis, the use of horizontal well drainage area, production pressure is small, with sand control, the edge of the bottom water features, full use of the hard-to-extract reserves of the block in order to achieve the purpose of raising the block mining degree, after analysis and demonstration And the production of horizontal wells have been drilled to prove that the utilization of horizontal well huff and puff development is the only mining method that can effectively use this block under the current technical conditions and has reference significance for the effective development of heavy oil reservoirs in Liaohe Oilfield.
