【摘要】：為了進(jìn)一步提高對潛山油藏的認(rèn)識(shí),對興古潛山開展了監(jiān)測工作,通過動(dòng)態(tài)監(jiān)測數(shù)據(jù)的對比分析,得到潛山油藏壓力變化規(guī)律,確定合理的工作制度、油藏類型,判斷地層連通情況及吸水能力,為該區(qū)塊開發(fā)方案及措施方案的制定與調(diào)整提供了依據(jù)。本文的研究內(nèi)容有:開展系統(tǒng)試井,通過監(jiān)測靜壓、流壓跟蹤油藏壓力變化;開展干擾試井,了解井間干擾狀況;開展壓力恢復(fù)測試,求取油藏儲(chǔ)層孔隙特征參數(shù);開展試注工作,通過分析研究注水指示曲線,落實(shí)儲(chǔ)層吸水能力。通過分析地層的壓力變化曲線來跟蹤油藏的壓力變化,在及時(shí)、準(zhǔn)確的掌握油藏壓力變化動(dòng)態(tài)且明確了壓力變化與產(chǎn)能的關(guān)系后,與系統(tǒng)試井相結(jié)合,目的在于合理調(diào)整自噴井的生產(chǎn)制度,保證自噴井的合理生產(chǎn),維護(hù)油井的自噴能力;通過分析油井之間生產(chǎn)的干擾數(shù)據(jù),證明井組之間和整個(gè)興古潛山不同段內(nèi)井間、段內(nèi)井間的連通情況。通過比較分析前后兩個(gè)年度的壓力恢復(fù)測試結(jié)果,得到該區(qū)塊滲透性、井周污染情況以及完井效果;通過分析啟動(dòng)壓力、吸水指數(shù)等數(shù)據(jù),落實(shí)興古潛山的儲(chǔ)層吸水能力和各項(xiàng)特性。
[Abstract]:In order to further improve the understanding of buried hill reservoir, the monitoring work of Xinggu buried hill reservoir is carried out. Through the comparison and analysis of dynamic monitoring data, the law of pressure change of buried hill reservoir is obtained, and a reasonable working system is determined. The reservoir type, the judgement of formation connectivity and water absorption ability provide the basis for the formulation and adjustment of the development plan and measure scheme of the block. The research contents of this paper are as follows: develop systematic well test and monitor static pressure. The flow pressure follows the change of reservoir pressure; Conducting interference well testing to understand the interwell interference situation; Carry out pressure recovery test to obtain reservoir pore characteristic parameters; Through the analysis and study of water injection indication curve, the reservoir water absorption ability can be implemented. The reservoir pressure change can be tracked by analyzing the formation pressure change curve, and the reservoir pressure change is in time. After accurately mastering the change of reservoir pressure and clarifying the relationship between pressure change and productivity, the purpose of combining with system well testing is to adjust the production system of self-blowout well reasonably and ensure the reasonable production of self-blowout well. Maintain the self-blowout capacity of the well; By analyzing the production interference data between wells, it is proved that the inter-well and inter-well connectivity between wells and between different sections of Xinggu buried hill is proved, and the results of pressure recovery test before and after two years are compared and analyzed. The permeability of the block, the pollution around the well and the completion effect are obtained. By analyzing the starting pressure, water absorption index and other data, the reservoir water absorption capacity and various characteristics of Xinggu buried hill are implemented.
