Abstract

The invention relates to a palm oil based pipe free agent and a preparation method thereof. The pipe free agent is composed of the following components in parts by weight: 4 to 6 parts of organic soil, 0 to 4 parts of filtrate loss reducer, 4 to 5 parts of emulsifier, 1 to 3 parts of rapid osmotic agent, 1 to 3 parts of oleic acid, 60 to 90 parts of base oil, and 0 to 30 parts of water phase. The pipe free agent has the following advantages: (1) environment-friendly and easily available palm oil is taken as the basic liquid of the pipe free agent, the obtained palm oil based pipe free agent has an excellent pipe free performance and the pollution to the strata is reduced; (2) a rapid osmotic agent is added, the soaking time of the pipe free agent is shortened, the shortage of long soaking time of other pipe free agents is overcome, and the pipe free efficiency is higher; and (3) the used reagents are sufficient on the market, the self made reagents are easily available, the raw materials are abundant and easy to purchase, the time for the pipe free operation is reduced, and the drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oilfield chemistry, in particular to a palm oil-based jam-releasing agent and a preparation method thereof. Background technique [0002] Drill sticking refers to the situation that the drilling tool is stuck in the wellbore and cannot operate normally during the drilling construction process. It is a common accident in the drilling process. Sticking can be divided into differential pressure sticking, sand sinking sticking, sand bridge sticking, keyway sticking, well collapse sticking and other types. Differential pressure sticking, also known as mud cake sticking sticking, is the most common way of sticking in drill sticking accidents. It refers to the difference between the pressure of the drilling fluid and the formation pressure after the drill string is adhered by the filter cake of the drilling fluid. caused by stuck drill. According to statistics, in some areas, the cost of dealing with different...
