Embodiment 1
[0035] Weigh raw materials: 10 g of oily drilling cuttings, 60 ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3.
[0036] Instructions:
[0037] Step 1: Place the weighed oily drill cuttings and leaching agent (60ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3) in a stirrer and stir for 7min at a shear rate of 300r / min;
[0038] Step 2: After stirring, let it stand for a period of time, wait for the solid phase to settle, the solid and liquid will separate naturally, then remove the lower layer, centrifuge the solid phase, and dry at 95°C for 24 hours;
[0039] Step 3: After the leached oily drill cuttings and the leaching agent are subjected to solid-liquid separation, the liquid phase is placed in a three-necked flask, and then distilled at a temperature of 120°C and a negative pressure difference of 0.01MPa to obtain emulsification Diesel and leaching agent.
[0040] The leaching agent in this example does not require s...
Embodiment 2
[0042] Raw materials were weighed: 10 g of oily drill cuttings, 58 ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3, and 2 ml of petroleum ether (boiling range: 60-90° C.).
[0043] Method of use: basically the same as in Example 1, except that the leaching agent is 58 ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3 and 2 ml of petroleum ether (boiling range is 60-90° C.).
Embodiment 3
[0045] Raw materials were weighed: 10 g of oily drill cuttings, 56 ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3, and 4 ml of petroleum ether (boiling range: 60-90° C.).
[0046] Method of use: basically the same as in Example 1, except that the leaching agent is 56 ml of polyoxymethylene dimethyl ether with a degree of polymerization of 3 and 4 ml of petroleum ether (boiling range is 60-90° C.).
