在油田生產過程中，原料和產品多為易燃易爆的物質，易發生事故，因此，對油井生產運行狀況、環境狀況、安全狀況的實時監測和控制，一直是油井的一項重要和困難的內容。
In the process of oilfield production, the raw materials and products are mostly flammable and explosive materials, which are prone to accidents. Therefore, the real-time monitoring and control of oil well production operation status, environmental conditions and safety conditions has always been an important and difficult content of oil wells.

不同儲層推薦做法
Recommended practices for different reservoirs
按儲層裂縫發育程度、孔隙性和滲透性，可分三類區別對待：
According to the development degree, porosity and permeability of reservoir fractures, it can be divided into three types
（1）儲層裂縫特別發育的井，這類儲層無論鉆井液密度高低，均會井漏，且漏速較大，對于這類井，建議參照在碳酸巖地區做法，采取快鉆強打、見好就收的方法。因為該類井儲層溝通很好，揭開較少也不會對單井產量造成較大的影響；相反如果鉆開較多，勢必會在噴漏同層的井段反復堵漏、鉆進，徒增井控風險和作業成本。
(1) For wells with specially developed fractures, no matter whether the density of drilling fluid is high or low, there will be lost circulation, and the loss rate is relatively high. For this kind of wells, it is recommended to adopt the method of fast drilling and strong drilling and close down when it is good, referring to the practice in carbonate rock area. Because this kind of well reservoir communication is very good, less uncovering will not have a great impact on the production of a single well; on the contrary, if more drilling is carried out, it is bound to repeatedly block and drill in the well section of the same formation with lost circulation, which will increase the well control risk and operation cost.
（2）裂縫不發育，但孔隙性較好的儲層，在近平衡鉆井獲得成功的前提下，建議再在成熟區塊探索欠平衡鉆井，具體做法是：先對不同井隊、不同鉆井公司和不同井位進行分級分類，然后選取“鉆井隊素質高+鉆井公司保障能力強”的隊伍，先期實施欠平衡鉆井，如果增產或縮短工期效果明顯，可在總結分析形成完善的技術規程后，逐步在大范圍內推廣超深高壓井欠平衡鉆井技術。
(2) For reservoirs with undeveloped fractures but good porosity, it is suggested to explore underbalanced drilling in mature blocks on the premise of success of near balanced drilling. The specific method is as follows: first, classify different drilling teams, different drilling companies and different well locations, and then select the team with "high quality of drilling team + strong support ability of drilling company" to implement underbalanced drilling in advance, If the effect of increasing production or shortening the construction period is obvious, the underbalanced drilling technology of ultra deep and high pressure wells can be gradually popularized in a large range after forming a perfect technical specification through summary and analysis.

在異常高壓情況下,附加了一個受滲透率變化影響的產量降低項,通過生產及測試數據繪制的油井指示曲線,在井底流壓高于飽和壓力時,曲線也要發生彎曲。同時建立了利用系統試井資料求取滲透率變化系數的方法 ,并對油田實例進行了計算 ,證實該方法具有一定的實用性，
In the case of abnormal high pressure, a production reduction term affected by permeability change is added. The oil well indicator curve drawn by production and test data will also bend when the bottom hole flow pressure is higher than the saturation pressure. At the same time, the method of calculating permeability variation coefficient by using system well test data is established, and the calculation of oilfield example shows that the method is practical,
